Re: [PATCH] console: use first console if stdout-path device doesn't appear

If a device tree specified a preferred device for kernel console output
via the stdout-path or linux,stdout-path chosen node properties there's
no guarantee that it will have specified a device for which we have a
driver. It may also be the case that we do have a driver but it doesn't
call of_console_check() to register as a preferred console (eg. offb
driver as used on powermac systems). In these cases try to ensure that
we provide some console output by enabling the first console in the
console_drivers list.

As I don't have access to an affected system this has only been build
tested - testing would be most appreciated.

Unfortunately that doesn't work.  The initial console still cannot be
opened.
